LIQUID AND GAS CONTACT APPARATUS.

This invention pertains to liquid and gas contact apparatus and has todo more particularly with the means employed to eliminate the moisturefrom the gas prior to its 15 leaving the apparatus.

More specifically," the invention pertains to an improved constructionof the moisture eliminator wherein the gas as'it passes from the zone ofcontact with liquid is caused to take a somewhat circuitous path and isthere brought into intimate frictional contact with a series of platesor a series of wires, or both, whereby substantially all entrainedmoisture will be removed and returned to the apparatus.

One embodiment of the invention-is illustrated in the annexed drawings,wherein:

Fig. 1 is a vertical sectional viewof. the upper portion of so much of ascrubber as is necessary to an understanding of the invention;

Fig. 2 a transversesectional view on the line 11-11 of Fig. 1;

Fig. 3 an enlarged vertical section of the eliminator proper; and

Fig. 4 a detail perspective view of the wires employed in or used as theeliminator.

The eliminator for the purposes of description is shown in conjunctionwith a liquid spraying element of the Feld type but it is to beunderstood that it is in no wise restricted thereto and that theeliminator may be used in connection with any type of scrubber.

In the drawings, 1 denotes the shell or casing through which extends avertical shaft 2 adapted to be rotated by any suitable means (notshown).

Secured to the shaft is a series of inverted 4o frusto-conical pumpingand spraying members 3, the outermost one of which adjacent its upperend is perforated. Said members at their lower ends extend down into theliquid within a pan or receptacle 4 and serve to withdraw the liquid andto spray the same outwardly toward and against the inner wall of thecasing. Such sprayed liquid is returned to the pan 4 by an annulardownwardly inclined shelf or deflector 5 extending around the interiorof the casing. Liquid is introduced through a suitable pipe 6. Theconstruction above described is typical of the well known Feld scrubberbut as will be evident, anyother means for securing an intimate contactbetween the sprayed or which is projected laterally by the pumping, andspraying elements 3, and thence to a. centrally disposed port or passage7. Said port or passage is formed centrally of an annular plate 8 whichinclines downwardly from the center port and is secured at its outeredge to the inner wall of the casing. The plate in effect forms thebottom of the eliminator chamber, while the upper section'of the easingforms the outer wall of said chamber,

said section being surmounted by a top or cover plate 9. An exhaust port10 extends through the side wall as indicated in Figs. 1 and 2.

' Extending upwardly from the inner edge of plate 8, say forapproximately half the extent of said edge, is a plate 11-,- said platebeing fastened to the cover 9, and at one end,'see Fig. 2, beingdeflected laterally and extending to one side of the gas exhaust port10. There isthus produced an eliminator chamber of tunnel formcommunicating at one end with port or passage 7 and at its opposite endwith exhaust port 10.

Any gas forced through the scrubber must of necessity pass through theeliminator chamber to port 10 and durin such passage it is desirable, todenude it of a 1 liquid which it may carry along. To that end there ismounted within the chamber a series of vertically disposed spaced plates12, the plates by preference (see Fig. 3) being held in such spacedrelation by top and bottom plates 13 and 14 to which they are secured.The plates are curved to conform to the cross section of the casing andpartition plate 11 and may be assembled as a unit and placed in positionas such.

While such plates will be found all sufiicient under ordinary conditionsto elfect the removal of the moisture from the gas by reason of thefrictional contact between said plates and the plates, I may positionbetween the plates a gas passing between the series of verticallydisposed wires. This may be readily accomplished by tying together aseries of vertically disposed and spaced wires 15 by means of horizontalstrands 16 and cross ties 17, the arrangement being the same at the topand bottom (see Fig. at).

Said fabricated wire structure may be placed in the spaces between thecontact plates 12 and held in such position by crossbars 18, Fig. 3,secured to the plates. Wires thus positioned will of course break up anybe seen upon reference to Fig. 3, the exhaust gas is caused to flow in aconstantly changing direction by reason of the fact that the eliminatorchamber and the plates therein are curved; hence a greater frictionalcontact inheres than would obtain were the tunnel or chamber straight.

What is claimed is:

In an apparatus of the character specified, the combination of a casing;a laterally curved chamber located at the upper portion thereof and incommunication at one end with the interior of the casing through apassage extending centrally of the casing, the chamber at its oppositeend being connected to a discharge port; a series of vertically disposedplates arranged in spaced relation within the chamber; and a series of'ver tically disposed spaced wires located between the plates.

In testimony whereof I have signed my name to this specification.

WILLIAM JOSEPH MOGURTY.
